Description

The invention relates to mechanical engineering and can be used for cleaning burrs on the external surfaces of parts.

The purpose of the invention is the expansion of technological capabilities by providing an additional effect on the processed parts of the oscillations of parts of the granules relative to each other.

Figure 1 shows a granule, a general view; figure 2 - section aa in figure 1; on fig.Z - granule with a decrease in width to the periphery.

The vibratory processing granule contains cutting edges 1 located along the working surfaces 2, the granule being made flat in the form of half rings interconnected on the central axis, and the radius of the half rings is increased towards the center of the granule, thus reducing the width of the working surface 2 granules in the direction of the periphery.

Make a pellet as follows.

Sheet material, for example steel 65G, is cut into strips from which a granule is made, for example, by cutting a die with simultaneous production of cutting edges 1 on the working surface. In addition, cutting edges 1 can be deposited on working surfaces 2, for example by electroplating, in the form of a diamond layer. The granule is ready to go. The dimensions of the granules depend on the dimensions of the workpiece, their weight, and material. The ratio of the thickness of the granules to its width b / v (figure 2) may be in the range of 1/10 ... 1/3. When the ratio of b / c is less than 1/10 and more than 1/3, the ability of the cutting edges 1 of different parts of the granule to vibrate, which leads to a decrease in processing performance, deteriorates. The weight of the granule can be 1-50 g, depending on the processing modes. Number polu5S

rings from 4 to 12, with a smaller number of half-rings, the vibrational properties of the granule deteriorate, and with a larger number, its manufacture becomes more complicated. The thickness of the material can be 0.3–3 mm to obtain the necessary vibration characteristics and preserve the deformation capacity. The radii of the half-rings (figure 1) can be 3-20 mm, depending on the dimensions of the workpiece, as well as the complexity of manufacturing and obtaining certain vibration characteristics. Changing the radius of the semirings is desirable in the range of ratios of semirings no more than 1: 3. The width of the half-rings depends on the vibration characteristics of the granule as a whole and its individual parts and can be 1-10 mm with a ratio of maximum and minimum width of not more than three times.

For example, the granule is made of 65G steel, 1 mm thick, the radii of half rings R 12 mm, R, 10 mm, Kg 8 mm, and the width of half rings 4 mm, the number of half rings 6, cutting edges 1 are made by applying a diamond layer by electroplating, the granule is made permanently width. The machining of parts is as follows. Pulp granules and workpieces are poured into the vibratory machine hopper. The machine vibrating device is turned on, the parts and granules are mixed and collided, the surfaces of the workpiece interact with the cutting edges 1 of the working surface 2, and the cutting edges 1 of individual parts of the granule additionally vibrate at different frequencies. As a result of the reciprocal movement of the pellet and the part, the burrs are removed. After the window- 45, they are filled in the form of half-rings of different diameters, rigidly connected along the ends directly with each other to form a flat, zigzag-shaped figure, while the half-rings of larger diameter are located in the middle part of the granule.

Stripping tubs shut off the vibrator, spilling the granules and parts and separating them.

The use of the described granules of the working medium for vibration treatment allows to increase the productivity of processing by increasing the surface of contact between the cutting edges of the granule and the surface to be treated by making the granule flat in the form of half rings,

interconnected along the central axis, increasing the vibration oscillations of the cutting edges of the granule as a result of increasing the radius of the half-rings towards the center of the granule with a possible decrease in the surface width, providing vibrational oscillations of various parts of the granule with

different frequency as a result of making different parts of the granules with different sizes, increasing the mobility of the granules by making the cross section of the granule in the form of a flat figure Pb1 with a possible decrease in the width of the surface of the granule towards the periphery, the additional movement of the parts of the granule in the form of twisting semi-rings relative to each other

Other, especially the peripheral half-rings relative to the central ones, increase the surface area of the granule, since the lateral surface is formed by half-rings.

5 The main advantage when using granules is that the technological capabilities are expanded by treating surfaces with grooves when they fall into semi-rings, increasing the sizes of machined surfaces as a result of making half-rings of different diameters, as well as chamfering, orbital holes semirings.
